iz claims. (cl. 164-111) V'I'his invention relates to perforated cardnumbering machines. More particularly it relates to machines forserially numbering successively presented cards by making perforationsin the cards I representing the numbers. It also relates to means forgang punching thecards or, in other words, for punching a group numberin successively presented cards.

One of the objects of the invention is to devise l mechanism wherebycards may be punched serially or serially in duplicates, triplicates,quadruplicates, etc.

vAnother object is to provide means for serially punching numbers incards up to a given number say nity and then repeating such numbeting soas to produce a number of groups oi cards all serially numbered from oneto fty or to some other desired number.

Another object is to provide means for punch ing common group numbers insuccessively presented cards in which the mechanism may be quickly setto control punching voi? the desired number and the parts locked in setposition so as not to accidentally change during the operation of themachine.

Another object is to provide a machine of this character which may beused as an attachment to a printing press in which tabulating cards areprinted and cut. p

These and other objects will be apparent from the following descriptionof the machine.

In illustrating my invention, I have shown a device which may beoperated in conjunction with a printing press or independently thereofand in which the actuation of the mechanism is effected by thereciprocationV of a bar 1 which may be operatively connected to aprinting press or to any other driving means. The bar 1 is slidablymounted in a bracket 2 xed to the base 3 of the machine. 'I'hetabulating cards which g5 are toA be numbered by this machine areproduced from a long strip of material 4 which is fed from a reel at theleft as viewed in Fig. 1, through the machine and is cut, preferably,after the printing and punching has been effected. Where the machine isused in conjunction with a printing press which is used to make up suchcards, the strip 4 is iirst fed through the press where the printing ofthe desired numerals and other data is effected. It is then fed into thegang punch and then into the serial numbering machine to have the serialor other numbering eiiected'in the form of perforations. Or if desiredthe strip 4 may be fed through the numbering machine rst and thenthrough the printing press. In either event the feeding through bothmachines will be coordinated so that the strip 4 will stop in suchposition as to receive the printing impression and punching in theproper locations. Such positioning means as Well as means for cuttingthe strip into separate cards is common in printing presses for makingup such cards and therefore need not be disclosed in the present device.

The strip of paper is fed between upper and lower die plates 5 and 6.Mounted in the upper 110 die plate 5 and also supported by a stationaryguide plate 7 are the punches 8 for perforating the cards. There aretwelve of these punches to each row or column and if there areforty-five columns there may be forty-five such columns of punches sothat prepunching may be eiected in any o1' the columns desired.

For convenience, I have shown the nine columns of punches at one end asbeing under control of the serial numbering device and all of the restof the columns of punches as being adapted to be used for punchinggroup'numbers in the cards. In Fig. 2 the nine columns oi' punches atthe right are the ones employed for serial numbering. Directly abovethese punches are interposer rods 9. There is one of these rods for eachpunch, or in other words, nine columns of twelve to each column. Asshown in Fig. 5, ten of the rods inv each column are of full lengthwhile two, i. e. those designated 9a are shorter. The rods 9a areadapted to cooperate with the punches for perforating in the 11th and12th positions on the card and are not used in serial numbering as onlyten are necessary for this purpose. The ten rods 9 reach upwardlythrough a guide plate 10 and then spread outwardly as shown in Fig. 2 soas to cooperate with pins 11 xed in rotors 12. There are nine of theserotors each having ten of the pins 11. Each of the pins is adapted tocooperate with one of the rods 9 and each of the rotors is associatedwith one of the nine columns of rods 9. The pins 11 are arrangedspirally on the rotor so that as the latter is turned step by step thepins will be moved successively into cooperative positions with respectto the rods 9. Thus assuming that a rotor is in such position that oneof the pins is in position directly above the upper end 9b of the rodassociated with the punch adapted to perforate in the 5 position in itscolumn of the card, rotation of the rotor one step lwill remove the 5pin from operative position and move the next pin over the rod 9associated with the punch that is adapted to perforate in the 4 positionon the card, etc.

In serially numbering a group of cards, I prefer to number them in adescending order so that they will be deposited with the card of thehighest number at the bottom of the stack and the lowest number at thetop. If it is desired to prepare a stack of cards numbered from 1 to100,000 the rotors l2 will be set so that the rst card punched will benumbered 100,000. After punching this card the rotors will be turned onepoint so that the next card will be numbered 99,999 and so on down. Thechanging is effected by turning the units rotor one point after eachoperation. The rotors are turned backward and when any rotor is turnedfrom 0 position to 9 position it effects a carry operation to the rotorof the next higher denominational order. Thus, when the units rotor isturned after the punching of the first card it causes the tens rotor toturn one point. As the tens rotor then turns from 0 to 9 position, itcauses a carry operation of the next higher rotor, etc., the hundreds ofthousands rotor turning from the 1 position to 0 l position, so that thesecond card will be punched The perforating of the card is effected bymoving the die plates 5 and 6 upwardly so as to press the card againstthe lower or cutting ends of the punches 8.

The card will then raise all of the punches except those that are helddown by the rOdS 9 and only those rods 9 that are directly under pins 11on the rotors will hold their rods down to prevent the correspondingpunches from being raised by the card. These punches then will perforatethe card.

In order to eiect raising of the die plates the latter are attached toside plates 13 which are adapted to be moved up and down. These platesare provided with studs or rods 14 with which slotted arms 15 cooperate.The arms 15 are fixed on rods 16 which bear in the side frame of themachine and pass through slots 17 in the plates 13 and the latter arefree to move up and down being guided by plates 13a. Also fixed on therods 16 are arms 18. These arms are interconnected by a. link 19 and atleast one of the arms reaches upwardly where it will be actuated by acollar 18a fixed on the rod 1. When the rod 1 is moved to the left asviewed in Fig. 2 the die plates will be raised so as to move the cardinto engagement with all of the punches to effect punching in thosepositions where the punches are held down byv the rods 9 in cooperationwith the pins on the rotors. Each time the rod 1 is moved to the left,collar 20 xed thereto is adapted to engage and to actuate an arm 21pivoted at 22 and connected by bell cranks 21a, 2lb and links 23, 23a toa pawl-carrying frame 24 loosely mounted on the units rotor l2 orconcentric therewith. The movement of the rod 1 to the left causes theframe 24 to be raised so as to turn a short distance in a clockwisedirection about the units rotor 12.

When the rod 1 moves to the right the rotor turning spring 25 lowers thelinks 23 and frame 24 and springs 87 lower die plates 5 and 6. The frame24 carries two pawls 26. These pawls are integral, being formed in theshape of a U or in other words, joined by the yoke 27 so that they rocktogether in the frame 24. A spring 28 tends to rock the pawls in acounterclockwise direction as viewed in Fig. 2 so as to cooperate with aratchet 29. When performing simple serial numbering only one of thepawls 26 is effective. 'Ihe other is used when more than one card ofeach number is desired as will be described presently. Each time theframe 24 is raised and lowered it turns the ratchet 29 one tooth spaceto shift the pins 11 to effect punching of the next numeral in thefollowing cycle of operation of the machine.

A leaf spring 30 fastened at 31 may be employed to engage the ratchet 29to impositively hold the latter in any position to which it is turned bythe pawl 26. Fastened to all of the rotors 12 excepting the one of theumts order is a star wheel 32 (see also Fig. 10) with which a spring 33cooperates to act as an impositive latch to latch the rotors in any setposition. Also fixed to each of the rotors is a wheel or disk 34 whichmay be provided` with ten flattened surfaces 35 bearing indications ofthe ten numerals which may be visible through openings 36 in a coverplate 37 as in Fig. 1. These visible numerals indicate the position ofthe respective rotors, that is, a numeral indicates that the rotor is inposition to eiect punching of that particular value on the card duringthe next operating cycle.

Referring to Fig. 1 carrying from one rotor to the next is effected bymeans of a one tooth gear 38 (see also Fig. 9) adapted to cooperate onceeach revolution with a tooth in the gear 39 mounted on the rotor of thenext higher order. Each of the rotors except the one of the highestorder is provided with a one tooth gear 38 to cooperate with a ten toothgear 39 on the rotor of the next higher order and each of the rotorsexcept the one of two circumferential grooves 41 as shown in Fig.

5 adapted to cooperate with a detent 42 pressed by a spring 43 into thegroove.

A knurled handle 44 is provided on the end of each rotor to permit theoperator to slide the rotor to either operative or inoperative position.The detent 42 will be cammed out of one groove and permitted to dropinto the next to thus hold the rotors in their operative or inoperativeposition. Resetting of the rotors may also be effected by moving them toinoperative position, demeshing gears 38, 39 and then turning them totheir zero or other desired position.

Punching duplicate numbers In order to punch two cards of each number abracket 45 carrying an additional ratchet wheel 29a is provided tocooperate with the second of the pawls 26 (Figs. 5, 6 and '1) Theratchet 29a is rotatably mounted on the plate 45 secured to the machineby screw 45a and is coaxial with the rotor 12 of the units order. Thisratchet is provided with ten teeth. Every other tooth or notch is ofsufficient depth to permit the pawls 26 to be moved inwardly asufficient distance to cooperate with the ratchet 29 xed on the rotor.Thus, when the frame 24 and pawls 26 are lowered the ratchet 29 will beactuated to turn the rotor one step. The intermediate notches in theratchet 29a are shallow so that when one of the pawls 26 is resting insuch notch the other will be held out of cooperation with the ratchet29. Then, when the fram 24 and pawls 26 are lowered the ratchet 29 willnot be actuated and the rotor will remain in the same position that itoccupied during the last cycle of operation and the same number will bepunched in the next card that was punched in the previous card. 'I'herotor of the units order will be turned one step every other cycle ofoperation of the machine so that throughout the entire operation ofserial numbering, two cards of each number will'be produced.

Punching three or more cards of each number In order to punch threecards of a number the ratchet 29a with plate 45 is removed and a ratchet29h on plate 45e (Fig. 4) put in its place. This ratchet is larger thanthe ratchet 29a, being pro` vided with twelve teeth and twelve notchesand is therefore mounted eccentrically with respect to the rotor 12. InFig. 4 every third notch in the ratchet 29h is a deep notch and the twointermediate notches are shallow. Thus, the pawl 26 which cooperateswith the ratchet 29h will turn the ratchet two idle strokes before it ispermitted to enter a deep notch to enable the companion pawl to engagethe ratchet 29 to actuate the latter.

Thus, ratchet 29 mounted on the units rotor will be actuated once foreach three cycles of operation of the machine. In this way, three cardsbearing each number will be produced. In Fig. 3 a ratchet wheel 29e onplate 45e is used in place of the wheel 29D. Ratchet 29e is providedwith a deep notch at every fourth tooth. This will cause the pawls 26 tooperate idly for three cycles and to turn the units rotor during thefourth cycle so that the serial number changes after four cards bearinga given number have been punched.

Serial numbering cards up to a predetermined number It is sometimesdesirable to produce a stack of cards numbered serially up to say 50 or100 or some other number; each stack being a repeti- -tion of the othersor in other words, each stack has cards numbered from 1 to 50 or from 1to 190 asdesired. To eect this punch numbering, I provide means tocontrol the rotors to serially number cards from 1 to the desired numberand then to commence numbering the next stack from the beginning.Preferably the cards are numbered in the descending order.

In the illustration in Fig. 12, I disclose a device adapted to effectthe numbering of the cards from 50 down to 1 and to then return tonumber 50 of the next stack, numbering the next stack from 50 to 1. Thedevice is adapted to keep up this operation as long as desired. For thispurposei the device is constructed as shown in Fig. 12 with the rotors12 of the units and tens order placed farther apart so as to permit theuse of the larger gear 39a on the rotor 12 of the tens order. The rotoro1' the units order is provided with two of the carrying gear teeth 38a,38h. The gear 39a. is of sufficient size to carry twelve teeth but isonly provided with ten, leaving two open spaces on opposite sides.

A mutilated gear 39D having but two teeth is xed beside the gear 39awith its teeth adjacent to the positions on the gear 39a from which thetwo teeth are omitted. The carry tooth 38a on the units rotor is adaptedto cooperate with one of the teeth in the gear 39a once each completerevolution of the units rotor, until it has actuated the tens rotor fivetimes. This will then bring one of the teeth 39D into position to beactuated by the other carrying tooth 38b so that on the next time aroundit will turn the tens rotor one step. The pins 11 on the tens rotor inthis instance are arranged in two groups corresponding to the punchesone to five. In other words, the pins in one of the groups will bringinto operation the punches from one to ve and the pins vin the othergroup will do the same. Both sets of pins are thus numbered from 1 to 5.In the operation of this device, the numbering will commence with therotor 12 of the tens order in such position that one of the 5" pins 11will be above corresponding column of rods 9 to punch 5 in the tensorder.

On the other hand, the 0 pin 11 on the rotor of the units order willcontrol punching for the rst cycle of operation numberingthe card 50.Then the tooth 38a will cooperate with a gear tooth 39a turning it onestep to bring into operative position the 4 pin 11 of the group to cause4 -to be punched in the tens order, the units rotor turning to 9.

The card numbered 49 will then be punched and deposited on top of thecard numbered 50. 'Ihe units rotor will then turn one step for each cardpunched until the card numbered 40 has been punched. Then as the unitsrotor is turned c-ne point the carry tooth 38a cooperating with one ofthe teeth of gear 39a will turn the tens rotor one step to bring the 3pin into operative position, the units rotor turning to nine position.This will cause card numbered 39 to be punched. The tens rotor will notbe turned again upon the carry tooth 38a will turn the tens rotoranother step bringing the two pin into operative position, the unitsrotor once more turning to the nine position. This operation goes onuntil a card numbered 10 has been punched after which the operation ofthe units rotor will move the tens rotor into position where none of thepins 11 will cooperate with the punches so that there will be nopunching in the tens column. The units rotor on the other hand wouldhave turned to the nine position to punch the card numbered nine. Theunits rotor continues to turn one point for each card punched until cardnumbered 1 has been produced. Now as the units i'otor is turned one morestep the carry tooth 38h cooperating with the carry tooth 39h will turnthe tens rotor one step bringing the five pin into operative position,the units rotor turning to zero position. The card numbered 50 of thenext group will now be punched.

It will be seen here that as the units rotor turns one more step to thenine position the carry tooth 38a cooperating with one of the teeth ofthe gear 39a will turn the tens rotor one s'ep to the four position. Thecard numbered 49 will now be punched. The operation will then continueas described punching the cards consecutively on down to card number 1of this second series and then a third series numbered from 50 down toone will be produced, etc.

If larger groups of cards` are desired, for instance, if the groups areto contain 60 cards, then the groups of pins 11 on the tens rotor may beincreased to six pins each, the number of teeth in the gear 39a and theposition of the teeth 39h being arranged accordingly.

Also if the groups are to contain 100 or several hundreds of cards thena 3rd rotor will be employed to control the punching in the 100s orderand appropriate carrying will be provided from the rotor of the tensorder to that of the 100s order. The manner in which this will becarried out will be suiciently obvious to those skilled in the art andtherefore need not be disclosed in detail here.

The 11 and 12 positions In serially numbering the cards only thepositions from zero to nine are. used; the punches for the 11 and 12positions remaining idle. There are instances, however, where it may bedesired to effect predetermined punching in the 11 and 12 positions. Forthis purpose rods 9a (see Fig. 5) are provided above the punches 8 ofthe 11" and12 positions. Above these rods is a slide 46 having threenotches 47 in its upper edge adapted to cooperate with a latching member48 carried by arms 49 and pivoted at 50. A spring 51 is provided to holdthe latching member 48 in cooperation with the notches in the slide 46.The slide is provided with a downward projection 46a adapted to be setover one or the other of the rods 9a to control the operation of the 11or l2 punches.

Gang punching In addition to serially numbering cards it is sometimesdesired to prepunch group numbers in the cards. In other words, forstatistical purposes, the cards are often divided into large groups andeach group is punched with the group number, all of the cards of a givengroup bearing the same group number. This number is ordinarily punchedwhen the other statistical data is being applied to the cards, but inmany instances, can be applied when the cards are being printed.

I have devised means in the present machines for prepunching these groupnumbers or to use the common language of the art for gang punching thecards.

Referring to Fig. 2 all of the columns of punches 8 except the nine atthe extreme right associated with the serial numbering are adapted" tobe used in prepunching group numbers. For this purpose a slide bar 52 ismounted above each column of punches. These bars are all provided withlongitudinal grooves so that they may ilt upon supporting bars 53. Theend of each slide 52 is provided with a downward projection 54. As shownvin Fig.. 5 the projection 54 is in its inoperative position and may beslid into position above any one of the twelve punches 8 so that whenthe die plates 5, 6 .with the card are raised against the punches, aperforation will be made in the position corresponding to the punchabove which the projection 54 is located. Wherever group number punchingis to be eiected the slides 52 in those particular co1- umns are movedinto position to control the proper punches. All of the rest of theslides are left in their normal or inoperative position. Those of theslides that have been set as well as those that have not are then alllocked in position so that they shall not move during the operation ofthe machine. For this purpose, all of the slides are provided withtwelve notches 55 in their lower edges. A locking bar 56 (Figs. 5 and11) is mounted on the frame member 57, being held by pins 58 fixed tothe member 57 and cooperating with diagonal slots 59 in the strip 56.

The slots are diagonally disposed so that when a locking bar is moved tothe right as in Fig.

11, it will be lowered to the position of Fig. 5. When it is moved tothe left, however, as viewed in Fig. 11, it will be raised from theposition of Fig. 5 into cooperation with the notches 55 in the slides. Apin or handle 56a is provided on the bar by which it may be adjusted.The slots 59 are provided with dwells at their lower ends to hold thebar in raised position. As shown in Fig. 1, the slides 52 may beprovided with designations corersponding to the 12 index point positionsin each column on the card. Directly under each designation is a shallowhole 60. To set the slide in position to eiect prepunching of aparticular numeral the operator will insert a stylus or pencil pointinto the hole 60 directly below the numeral which is to be punched inthat column and move the slide downwardly as far as he can. Slidablymounted over the slides 52 is an index nger 61 reaching the full lengthof the slides 52 and carrying designation numerals corresponding to theindex points on the card. Each numeral on the index iinger is adjacentto the hole 60 in the slide corresponding to the particular numeral.Thus, besides having the numerals on each slide the operator also hasthe benet of the numerals on the index linger to show him where toinsert his stylus. The index finger 61 is mounted on a rod 62 (see alsoFig. 2) and is adapted to be moved to the right or left. A springactuated detent 64 xed with respect to the index finger is adapted tocooperate with notches 65 across the upper part of the rod 62. There isone of these notches for each slide 52. A lever 66 pivoted on the indexfinger reaches under the detent spring 64a at one end and may bedepressed at the other to lift the detent out of the notches 65 so thatthe index ilnger may be readily moved toward the right in Fig. 2

A cam edge 67 is provided on the index ilnger to be engaged by thestylus as it is moved downwardly with the slide. This will move theindex finger one step to the left as each slide is set so that it willuncover the next slide 52 to be set. In this way, the operator sets theslide lying immediately to the right of the index linger and the indexfinger is automatically moved one step to the left when the slide isset. In camming the index finger to the left the stylus nally lodges inthe lower portion of the notch 68. The index ringer will thus be movedto the left until the upward projection 69 engages the stylus.

- It is sometimes desirable to punch more than onehole in each column.For this purpose the slides 52 may be made thinner and more than one maybe provided above each column of punches. I have shown other means,however, in the present instance, for effecting punching of a pluralityof holes in a single column. As shown in Figs. 1 and 5, two setting pins.70 are slidably mounted between the supporting bars 53 for each columnof punches 8. In Fig. 5, these pins are shown to the left and may bemoved to the right into position above thedesired punches. Suitablemeans may beA provided to hold these pins in position so that theywill-not be accidentally moved. For this purpose, each of the pins 70may be provided with a hole 71 as shown in Fig. 1 and a plate 72 shownin Fig. 13 may be provided to lock the pins in-position.

The plate 72 has downwardly projecting V- pointed locking pins 73corresponding to all of the positions to which the pins 70 may be movedas well as to the inoperative positions which they normally occupy. Thisplate may be placed in position above the pins 70 so that the pins 73will lodge in the holes 71 to lock all of those pins 70 which have b'eenset, in position, vand to lock all of those that have notfbeen set, intheir inoperative positions. y

`Two positioning holes v74 are provided in the plate 72 to cooperatewith slotted studs 75 carried by the frame of the machine. Latches 74amay be provided to cooperate with studs 75 to lock plate 72 in position.When none of the pins 70 are to be used a separate locking plate76 alsohaving latches 74a (Figs. 14 and 15) may I'be placed over the pins 70,the holes 77 cooperating with the studs 75. The ilange 78 will reachdownwardly over the edge of the pins 70 to prevent them fromaccidentally moving into position above the punches. Instead of using anindex similar to finger 61 a plate 79 such as shown in Fig. 16 may beemployed. This plate is provided with a downwardly reaching flange 80adapted to lodge in a groove 81 (see Fig. 1) in the frame of themachine. notches 82 in its edgescorresponding to the several punchingpositions. The operator may insert his stylus in oneof the holes 71 inthe setting pins 70 moving the slide to the approximate l position andthen move the plate 79 againstfthe stylus so that it will lodge in theappropriate notch 82 and be accurately adjusted to proper position.

The punches 8 are cut on one side to provide shoulders 85, and bars 86are provided toengage these shoulders. The bars are raised and loweredwith the die plates 5, 6 to positively lower the punches to normalposition. Springs 87 serve to lower the die plates.

The plate 79 is provided withA While there has been shown and describedand pointed out the fundamental novel features of the invention asapplied to a single modification it will be understood that variousomissions and substitutions and changes in the form and details of thedevice illustrated and in its operation may be made by those skilled inthe art without departing from the spirit of the invention.
